Platform-surface-quickly-detachable high-precision automatic checkweigher

Abstract

The invention discloses a platform-surface-quickly-detachable high-precision automatic checkweigher. The platform-surface-quickly-detachable high-precision automatic checkweigher includes an electric box, a weighing sensor, a rack and at least one weighing platform arranged on the rack; the weighing platform includes a platform frame and a platform surface, wherein the platform frame is fixedly arranged on the rack, and the platform surface is horizontally and fixedly arranged on the platform frame through a plurality of fastening devices; the electric box located at one side of the platform surface and is fixedly connected with the rack in a positioned manner; the weighing sensor is arranged on the platform frame and is electrically connected with the electric box; one surface of the rack, which backs the weighing platform, is provided with a plurality of bottom feet; the platform surface can be adjusted to be horizontal through the bottom feet; the platform surface is a mechanically-machined piece; and the mechanically-machined piece is an aluminum piece of which the thickness is 10 mm. With the platform-surface-quickly-detachable high-precision automatic checkweigher of the invention adopted, the platform surface can be detached quickly; mechanical and electrical repair can be facilitated; disassembly time in repair can be shortened; the parallelism of the platform surface can be improved; and weighing error caused by the deformation or vibration of the platform surface can be avoided.

Description

technical field [0001] The invention relates to an automatic checkweigher, in particular to a high-precision automatic checkweigher whose table top can be quickly disassembled. Background technique [0002] A checkweigher is a weighing instrument that automatically weighs discontinuous component loads. The automatic checkweigher can check the weight of the weighed object according to the preset area limit value. When the weight of the weighed object exceeds the allowable upper limit and lower limit, it will automatically detect the out-of-tolerance object, and can Automatically remove it from the production process and send out an audible and visual alarm signal. At present, automatic checkweighers have been used in the fields of food, medicine, chemical industry, machinery industry, and agricultural and sideline products. With the construction of large-scale enterprises, the requirements for modern management level are also increasing, and people will realize the advantage...

Problems solved by technology

[0003] The automatic checkweigher usually includes a load cell, an electric box, a weighing platform and a frame. The load cell is electrically connected, which can amplify, calculate and process the weight signal sent by the load cell, and digitally display the weight value, and compare the weight data with the preset value, and then send out underweight, overweight, and qualified control signals; At present, the countertop of the weighing platform of the automatic checkweigher usually uses sheet metal parts. Due to the technological problems of the sheet metal parts, the parallelism of the countertop is not very accurate, and the parallelism of the countertop directly affects the accuracy of the checkweigher, so there is a weighing accuracy. The problem is that the countertop material is usually made of stainless steel, which has the possibility of vibration and deformation of the countertop, and is heavy, which is not conducive to mechanical debugging and electrical debugging. In addition, multiple bolts are usually used to fix the connection between the countertop and the bench, mechanical and electrical In terms of maintenance, disassembly is cumbersome, resulting in longer maintenance time
